A curated collection of common Ruby idioms with benchmark comparisons showing which constructs run faster, inspired by Erik Michaels-Ober's 'Writing Fast Ruby' talk. Each idiom includes runnable benchmark code using benchmark-ips, with results regularly re-run against new Ruby versions.
Use cases
- speed up slow ruby code
- compare ruby idioms performance
- learn which ruby methods are faster
- find faster alternatives to gsub
- benchmark ruby code snippets
- optimize ruby hot paths
When to choose
- you want evidence-based performance comparisons between Ruby idioms
- you are learning to write more performant Ruby
- you need copy-paste benchmark templates with benchmark-ips
When to avoid
- you need an automated static analysis tool (use fasterer instead)
- you need a benchmarking library itself (use benchmark-ips)
- you need guarantees - the repo itself warns idioms depend on context
